SHOE HEEL.

Application filed June 28,

This invention relates to an improved shoe heel of the type composed ofa leather lift and a rubber lift, wherein the rubber lift is detachablyconnected with the leather lift so that when it becomes unduly worn, itmay be removed and replaced by the wearer in order to obviate thenecessity of employing a skilled repair man for attending to this.

My principal aim is to generally improve ipon structures of this classby providing one wherein the means for connecting the two lifts togetheris structurally different and novel from similar devices with which I amfamiliar.

My principal object is to provide a comparatively simple structure ofthis kind wherein two metal plates are provided and attached to themeeting faces of the two lifts, these plates being provided with novelcoacting means for facilitating interconnection of the two lifts, butpreventing accidental separation thereof.

Other features and advantages of the invention will become apparent fromthe following description and drawing.

In the accompanying drawing forming a part of this application and inwhich like numerals are employed to designate like parts throu bout thesame:

Figure 1 IS a longitudinal section through a heel constructed inaccordance with the invention, showing the manner in which the partscooperate.

Figure 2 is a transverse section through the same.

Figure 3 is a perspective view of the leather lift inverted.

Figure 4 is a perspective view of the rubber lift.

In the drawing, the reference character 1 designates a part of a shoeupper and 2 designates generall the heel which is made up of the leatherIi 3 attached to the upper and the rubber lift 4. which is in turnattached to the leather lift.

Referring now to Figures 3 and 4 it will be seen that the leather lift 3is provided on its under side with a metal late 5 of a shapecorresponding to that of t e lift but of asmaller size. This plate hasits marginal edge formed to provide a substantially U- shaped guide andretaining channel 6. In addition, it is provided at its center with alocking tongue 7 which is struck out in the manner shown.

1926. Serial No. 119,105.

The rubber lift is provided in its top with. a recess to accommodateanother complemental plate 8 of shape and size corresponding to that ofthe first named plate 5. The depth of the recess is equal to that of thethickness of the plate so that the surface of the plate is substantiallyflush with the to surface of the rubber lift. In addition t is lift isprovided with a groove 9 extending around the marginal edge of the plateand in this connection it will be noted that the marginal edge overliesthe groove as indicated at 10, thus providing a retaining flange adaptedto be slidably received in the channel 6. At its center, this plate isformed with a rectangular opening 11 and one end wall of the metal isrovided with a depending tongue 12 and tl fe laterally extending lip 13forming a keeper for cooperation with the aforesaid retaining tongue 7.It will be noted that the rubber lift is provided here with a pocket 14to accommodate the tongue 7 Moreover, a hole 15 is bored through therubber lift and communicates with this ocket and is adapted to receive aremovable lnstrument 16 of an appropriate nature for disconnecting thelocking tongue from the keeper.

In practice it is obvious that the leather lift is fastened to the shoeupper in the customary manner, and then the rubber lift is slid in placeby aligning the curved end of the plate 8 with the entrances to thechannel 6. As the lift 4 is slid into place it is obvious that theresilient locking tongue 7 automatically snaps intothe opening 11 andengages the keeper formed by the parts 12 and 13. It is then impossibleto se arate the lifts until the tongue is disengage from the keeper andin order to do this it is necessary to insert an instrument 16 throughthe hole 15 and to engage it with the tongue and to press the tongueupwardly so that it will clear the upper surface of the plate 8 as therubber 11ft is slid in a direction from left to right in the drawing.

From the foregoing description it is obvious that I have evolved andproduced a novel connection between separable rubber and leather liftsforming a shoe heel, the gist of the invention residing moreparticularly in the positive locking connection between the two plates,whereby the lifts may not be separated until the tongue is disengagedfrom the keeper.

No doubt by considering the description and drawing, a clearcomprehension of the invention will be had.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent is In a heel structure of the class described,a leather lift, a plate carried by said leather lift and provided with amarginal channel of substantially U-shaped design, a rubber lift formedin its top with a recess having a imarginal counter groove, a secondmetal plate carried by the rubber lift and located in said recess, theedge portion of said second plate overhanging said groove, the groovebeing adapted for reception of the channel, and said channel beingadapted for meme? reception of the marginal overhanging portion of saidsecond named plate, a down bent resilient locking tongue carried by thefirst named plate, said second named plate having an opening for passageof said tongue and one edge of the opening carrying a keeper ofsubstantially right angular formation, the portion of the rubberadjacent said keeper being formed to provide a pocket for reception ofsaid tongue, and said rubber lift also being provided with a verticalhole coinmunieating with said pocket and adapted to permit passage ofsuit-able means for forcing said tongue upwardly to permit said platesto be disconnected.

In testimony whereof I afiix my signature;

ALFRED l3. DUCHENEAU.
